I've asked Gael, a couple of times, when he is going to release the lower stomach parts and he has said that he is not happy with the design and may have to change it. He wants it to be correct the first time so people don't have to modify it in the future.

@Aerius Ah sorry dude... I had something similar happen to me... I tried an experiment... which turned out to be very dumb... Hey hindsight is 20/20 right.... I decided to write a script that would set all my servos to position 0 (yes, I mean zero) thinking it would work as an auto release... well it didn't and it broke the left shoulder piv gearbox by trying to over rotate backwards... Even thought I print exclusively in ABS it still broke... So I had to re-print the entire left shoulder (as you know the piv joint connects solidly to the rot joint)... So I had to reprint both gear boxes and connectors...
